========   Active / primary path
--------   Standby path for Chassis #1
........   Standby path for Chassis #2

Distance between SITE A / DC-A and SITE B / DC-B is 30KM.

Protection Logic
----------------
• Provider-A is the normal working path for both chassis
• Chassis #1 fails over from Provider-A to Provider-B
• Chassis #2 fails over from Provider-C to Provider-D
• Each chassis has only one standby provider
• Switchover occurs on path failure or degradation
• Target switching time of the path switchover <50ms


Technical Requirements
----------------------
• Minimum 2x SAN 32Gb/s ports and 2x 25G network ports per chassis (transceivers should be included). Ability to add additional client ports 2x SAN 32Gb/s ports and 2x 25G network ports.
• Each Chassis should support two independent links for redundancy
• Solution should support data encryption
• Each chassis should have redundant power supply
• Solution should support automatic protection switching without manual intervention
• Solution should support reliable operation between two data centers separated by approximately 30 km of fiber distance without any intermediate hardware
• Each chassis should support minimum aggregate throughput 200Gb/s. Ability to increase throughput capacity without requiring hardware upgrades will be considered advantageous.
• Solution should have comprehensive monitoring functionality

24/7 vendor support. Customer should have ability to independently open support tickets.
